Sequence Of Turning Off Power Supplies; Timing - Panasonic FP2 S-LINK Technical Manual

5.2 Sequence of Turning Off Power Supplies

• When ftuning off the power supply to the main unit (FPΣ), always turn off the main unit power supply
before turning off the S-LINK main power supply.
• If using a local power supply, always turn off the power supplies in the following sequence: main unit →
S-LINK main power supply → local power supply (or turn off the main unit → S-LINK main and local
power supplies at the same time).
• If using the booster local power supply, turn off the power supplies in the following sequence: main unit
→ S-LINK main power supply → booster local power supply ( or turn off the main unit → S-LINK main
and booster local power supplies at the same time).
Note:
• When turning off the power supplies, any S-LINK devices being run from a local power supply will stop
operating when the local power supply is turned off, and this causes a disconnection error.

5.3 Timing

After the power supply for the FPΣ system is turned on, with the external power supply for the S-LINK
already on, it takes approximately 1.8 seconds for the S-LINK input/output data to be refreshed.
A timer or similar device should be used to boot the program, so that the program boots after the data
has been refreshed. Make sure an adequate time period is taken into consideration, allowing time after
booting the system for S-LINK input to pass through the b contact, and other operations to be completed.
